39 Self-sensing Commutation
Startup Error
40 230V Shunt Protection Fault
41 460V Shunt Protection Fault
42 Motor Keying Error
43 Drive Enable Input
50 Duplicate Node Fault
All others RESERVED
U l t i m a S V
Probable Cause
Motion required for self-sensing
startup commutation was
obstructed
Ineffective shunt resistor
Excessive regeneration
Ineffective shunt resistor
Excessive Regeneration
The motor physically connected
to the drive differs from the
motor specified in the user pro-
gram
• An attempt was made to
enable the axis through soft-
ware while the Drive Enable
hardware input was inactive
• The Drive Enable input tran-
sitioned from active to inac-
tive while the axis was
enabled
Duplicate node address
detected on SERCOS ring

Corrective Action
• Verify that there are no
impediments to motion at
startup, such as hard limits
• Increase self-sensing current
if high friction or load condi-
tions exist
• Check motor or encoder wir-
ing using wiring diagnostics
• Verify that the shunt resistor
(internal or external) is con-
nected
• If an external shunt resistor is
connected, verify that the
shunt fuse is not blown
• If a non Allen-Bradley exter-
nal shunt resistor is used, ver-
ify that the resistance value is
within specifications
• Verify that the motor is not
being driven mechanically,
causing the motor to behave
as a generator.
Select the correct motor in the
user program
• Disable the Drive Enable
Input fault
• Verify that Drive Enable hard-
ware input is active whenever
the drive is enabled through
software
Verify that each SERCOS drive
is assigned a unique node
address
